I've worked extensively with payment providers like Stripe and Braintree.
I'm one of the lead developers for Gratipay.com, a company that aims to solve the funding problem in open source. We've processed $1m+ over the last 5 years. I've worked on the core payments infrastructure for Gratipay, including moving from Balanced Payments to Braintree.
I've also worked on a lot of custom payment implementations for clients - including ones that include variable billing, gift cards/credits, referral programs etc.

I am a software engineer with over 10 years of experience in developing enterprise solutions.
I work with my clients from the concept to delivery, including requirement analysis, solution architecture, implementation, quality assurance, delivery, deployment and maintenance. All the lifecycle of an application is closely followed to guarantee an high quality product.
I have experience in working with clients from around the globe, from Macau to the United States, Portugal, Spain, Netherlands and others, in business areas ranging from Financial Markets to Health and Insurance, Technological Startup and others.

I create strategic solutions for complex technology products and challenging business problems.
I am an innovative technologist with 10+ years of experience in delivering outstanding results for an illustrious clientele. I was recently honoured to be featured amongst the Top 20 Technologists Globally by The New York Observer.
